The Zeiss Compact Prime CP.2 21mm/T2.9 ZF Nikon Mount Lens is a high-end, commercial-use lens that is smaller and lighter than many professional cinema lenses. It has a robust cine-style housing that can easily accommodate a follow focus unit with standard focus and iris gear positions. It is designed for full frame cameras but has a sweet spot effect on Super 35 sensors. This lens is contrast-ready for 4K shooting and is ideal for documentarians, narrative filmmakers, and even studio photography. It is wide enough for very tight interiors and for expansive outdoor scenes.
